Keeping Ukraine's war effort up could be too heavy a lift for Europe alone if Republicans break US support

"Russia's military supply situation has been steadily improving," Justin Bronk, a senior research fellow for airpower and technology in the military sciences team at Royal United Services Institute, wrote last week in a RUSI blog. "Artillery ammunition production has almost doubled, and has recently been supplemented by over 1 million shells and hundreds of howitzers from North Korea," he wrote. North Korea worked a deal with Russia earlier this year to support its war effort in Ukraine reportedly in exchange for food, petroleum products, and advanced military technologies.
